OSN
The OSN was Anastasio Somoza's secret police unit that monitored political dissidents during the Somoza dynasty's rule over Nicaragua.
The OSN (Oficina Seguridad Nacional) was Anastasio Somoza's secret police unit that monitored political dissidents during the Somoza dynasty's rule over Nicaragua. The organization was part of the repressive apparatus that kept the Somoza family in power for 43 years and produced many of the officers who later formed the Contra army after the Sandinista revolution.1
Legacy
The OSN's intelligence officers, trained at U.S. military schools including Fort Gulick, Fort Benning, and Fort Leavenworth, brought their surveillance and counterinsurgency skills to the Contra war. The culture of political repression and intelligence operations that defined the OSN carried over into the FDN's operations, where former National Guard officers applied the same techniques against the Sandinista government. The Meneses family's connections to the Somoza intelligence apparatus, including the OSN, facilitated their later role in cocaine trafficking and Contra fundraising.2
